in a moment we'll hear from the protester from across europe, angry because they feel leaders are failing to solve many issues threatening world peace. first, from hamburg, jon sopel. the famous port of hamburg, tonight a disembarkation point for anarchists, anti—capitalists, anti—globalisation protesters, and the leaders of the world's 20 richest nations. protesters‘ stones and fireworks were met by police tea rgas and water cannon. no such hostility when the president ventured out in warsaw this morning. not everywhere in europe would they chant donald trump's name so loudly or so approvingly. but with its populist anti—immigration government, this was politically the ideal place to come. and by dint of poland's history and geography, the perfect location too to deliver a message about the challenges facing the west.

the fundamental question of our time is whether the west has the will to survive. do we have the confidence in our values to defend them at any cost? do we have enough respect for our citizens to protect our borders? do we have the desire and the courage to preserve our civilisation in the face of those who would subvert and destroy it? in the 1940s, the threat was nazism. this sculpture commemorating those who died in the warsaw uprising, the backdrop on which the president delivered his speech. today he identified the threat as islamist extremism, but he had another target in his sights too. we urge russia to cease its destabilising activities in ukraine and elsewhere and its support for hostile regimes, including syria and iran, and to instead join the community of responsible nations in ourfight

against common enemies and in defence of civilisation itself. that's the most outspoken he has been about russia and it comes on the eve of his eagerly anticipated first meeting with vladimir putin. but on moscow's interference in last november's us presidential election, something his intelligence services say is fact, the president again equivocated. the president again equivocated. it could very well have been russia, but it could have been other countries and i won't be specific. but i think a lot of people interfere. it's been happening for a long—time, for many years. then it was onto germany and what promises to be at testing summit, with disagreements over trade, immigration and climate change. the world's leaders aren't exactly welcome in hamburg.

there are tens of thousands of protesters in the city, they dance to many different tunes but they are united in their resistance to this summit. then, after a peaceful afternoon, police moved into disperse them. within minutes, stalemate. this is now stand—off for a half an hour or so. the police in riot gear, water canon at the ready have been waiting here, holding back the demonstrators, who say they are not going anywhere. hard to say who provoked whom but this is exactly what police feared. they say 8,000 extremists are targeting the summit, many of them armed with improvised weapons. the demonstration maybe over for now, the protests are not. we are shocked how the police

is treating all the people and we saw how scared the people are. they are just doing theirjob but maybe a little sometimes too hard! this evening this city is uneasy, after all, the summit hasn't even yet gun. the summit hasn't even yet begun. jenny hill, bbc news, hamburg. i've been speaking tojohn blaxland, professor in intelligence studies and international security, at the australian national university. he told me how he thought donald trump's political style will go down at the 620. i think one thing about the trump administration is a degree of dysfunction. we here in speaking in a belligerent manner and then secretary of defence trying to rein

him in. trump knows that the rhetoric is not going to get him very much that his playing the game. but matters knows —— mattis knows an escalation is in nobody ‘s interest. the rhetoric that the trump administration has been using with china has been mixed and so the meeting which president trump will have with president xi xingpin will be mixed. it is in a mix of other issues as well. the protesting outside the 620 summit is perhaps symptomatic of the tussle of what is going to be happening inside. we're talking about security, trade, climate. all of these things. and refugees. these are things which the

united states under trump is not in agreement with europe nor with china and russia in many cases. when we think in terms of climate, it is clearly a point of contention. trump is not a believer in that. on trade, we have the us who has been the leader of the world trade organization, leader of the world trade 0rganization, it has been is directly at the front runner on trade liberalisation acting more as a protectionist. and europe and japan coming up with trade agreement. there are clear ramifications for the us trade wise. the most significant is on the security front and it is notjust north korea. north korea is certainly a big one. what happens with syria, the talk that secretary tilson has made about some kind of

deal with russia can about the rhetoric from president trump suggest it is not all that likely. it isa suggest it is not all that likely. it is a chasm development between russia and the us. what he has said in poland indicates he is not feeling too warm towards russia partly because of domestic reasons. they write conflicting messages which are problematic for the 620 summit. here's hoping something constructive will come out of it, given that the leadership we have seenin given that the leadership we have seen in europe, particularly from angela merkel and emmanuel macron in france. and also xi xingpin, from china could also change the light of things. let's take a look at some of the other stories making the news: the world health organization has issued a stark warning that the sexually transmitted infection, gonorrhoea, is rapidly developing resistance to antibiotics.

in a study of 77 countries, the who found cases injapan, france and spain where the infection was completely untreatable. british counter terrorism police say they believe salman abedi, who carried out the suicide attack in manchester in may, was not part of a larger extremist network. but officers say other people might have been aware of what he was planning, and they want to question his younger brother, who is in custody in libya. the chinese hospital treating imprisoned nobel peace laureate, liu xiaobo, says his condition has worsened. the dissident was diagnosed with late—stage liver cancer in may. he was imprisoned in 2009 on charges of inciting subversion against the state, after he helped to write a petition calling for political reform in china. authorities in mexico say at least 28 inmates have been killed in a prison riot in the coastal city of acapulco. three other people were wounded. security officials said the fight was between rival gangs. it's the latest example of an upsurge in violence that has made 2017 one of the bloodiest in mexico's recent history. 6reg dawson reports.

as police prepared to enter the prison with protective clothing and riot shields, it provided a small clue as to the level of violence happening inside. it was in the early hours of thursday morning when some inmates on the maximum security wing broke out of their cells and began fighting. victims were stabbed and beaten to death. local reports claim some of the dead were decapitated. bodies were strewn around the kitchen, the prison yard, and the conjugal visits area. this most brutal attack in one of mexico's most violent cities. las cruces prison is supposed to be heavily overpopulated, with over 2000 inmates. as relatives of the inmates got word of what was happening, some tore down the security fence to try and reach loved ones. a spokesman said the fighting was triggered by a permanent feud between rival gangs within the prison. acapulco used to be one of mexico's most popular beach resorts.

but tourism has given way to vicious gang warfare, and it is now ranked one of the most murderous cities in the world. the timing of the riots has been particularly embarrassing for the mexican government, who are hosting the us department of homeland security secretary, john kelly, the same day. the trump administration has a ready made its concerns about violence security in mexico clear. this is likely to only add fuel to that debate. 6reg dawson, bbc news. it's a project that's been two decades in the planning and a journey that will take 7 years to complete but european and japanese scientists say their mission to mercury will finally leave the launch pad next year. two spacecraft will travel the nearly 80 million kilometres together, but then separate on arrival to conduct their own studies in temperatures above 400 degrees c. here's our science correspondent rebecca morelle. a mysterious world, mercury is the smallest planet in our solar system, and the closest to the sun.

covered in craters, towering cliffs and ancient volcanoes, until now, it has been little explored. a major new mission is set to change that. this is the spacecraft called bepicolombo, named after a famous italian scientist. it has taken nearly a decade to build. it is only when you get up close that you really get a sense of the size of this huge piece of kit. and this is a spacecraft built to withstand extremes. to get to mercury, it has to travel towards the sun, and that means dealing with intense radiation and heat. 0n the surface of mercury, temperatures can reach a50 celsius, and that's hot enough to melt lead. its launch will take place next year. this is probably one of the most challenging missions we have ever undertaken. it's the long journey to get there and then we have to deal with heat when we get close to the the sun.

but mercury is a tiny, enigmatic little world, which has so much to tell us about the formation of our solar system. bepicolombo‘s journey will take seven years, arriving at mercury in 2025. once it's there, the engine will be jettisoned, and two spacecraft will separate. they will work together to give us our best ever view. we'll see its features in incredible detail, and peer inside to solve the mystery of what lies at mercury's core. this is the instrument we built at the university of leicester... british scientists have developed x—ray cameras for this mission. we're going to be the first people on the planet to see this data coming back from mercury. we'll be the first people to see x—ray images of mercury's surface, which is going to tell us about what the surface is made of, and it's going to revolutionise our understanding. the spacecraft will soon be packed up, ready for its long journey. and while it will be sometime before we get the first results back, scientists say the will be worth it. scientists say the wait

will be worth it. rebecca morelle, bbc news, the netherlands. stay with us on bbc news, still to come: living the high life — the restaurant in los angeles that's recreating the experience of aviation‘s golden age. central london has been rocked by a series of terrorist attacks. police say there have been many casualties, and there is growing speculation that al-qaeda was responsible. 6ermany we will be the hosts of the 2006 football world cup. they pipped the favourite south africa by a single vote. in south africa, the possibility of losing hadn't even been contemplated. celebration parties planned in all the big cities were cancelled. the man entered the palace through a downstairs window and made his way to the queen's private bedroom. then he asked her for a cigarette, and on the pretext of arranging for some to be brought, she summoned a footman on duty, who took the man away.

one child, one teacher, one book and one pen can change the world. education is the only solution. this is bbc news. the latest headlines: police in germany have clashed with protestors as world leaders gather in hamburg ahead of the 620 summit. as he arrived in europe, president trump called on the west to defend itself against the threat of islamist terrorism. let's stay with the 620. and a warning from the former prime minister of australia, who helped shape the summit into the gathering it is today. kevin rudd told the bbc the world is entering a dangerous phase. i think there are two levels of risk.

one is the geopolitical risk level. we've seen what's unfolding on the korean peninsula, with the new environment, with the testing for the first time ofan icbm. in us—russia relations there is now an increasing incidence of russian and us military aircraft having near misses or near incidents, either in the baltic or across the middle east. and then thirdly uncertain trajectories now again from a different source of tension in the middle east. finally, geoeconomics. we now have the deep pressures which now exist on the future of free trade and if we end up in a trade war through tariff action and counter tariff action, that's bad news for growth and bad news forjobs. the us and russian presidents will hold their first face—to—face talks on the sidelines of the summit.

mr trump has already said he wants to find ways to work with vladimir putin, but what do ordinary russians think of him? for the most part they think less of him now than when he took the oath of office six months ago. in fact, a cossack community in st petersburg who had made him an honorary member, has since withdrawn that status. steve rosenberg has more. are you disappointed in donald trump? yes. when donald trump became president, there were great expectations in russia. are you disappointed in donald trump? yes. i understand he is on top position. because everytime he says something or hear something, he to improve relations with russia, and he is accused of being a russian stooge.

steve rosenberg with that report. china's only aircraft carrier has arrived in hong kong in what is being seen as a show of force to its rivals in the contested south china sea. the soviet—made liaoning and its three accompanying warships entered hong kong waters from the south. the carrier will stay for two days. earlier this week, 2000 hongkongers queued for hours to get tickets to board and visit the ship. france's environment minister — nicolas hulot — has christened the first ever boat to be powered solely by renewable energy and hydrogen. the ‘energy 0bserver‘ is covered in solar panels and has two wind turbines on either side

of the cabin to power it. when there is no sun or wind the boat will use hydrogen as a fuel. the crew are now planning a fifty—country tour to raise awareness about the project. it's one of the world's most enduring aviation mysteries, the disappearance of american pilot and pioneer amelia earhart. now, some are suggesting an old photograph could be shedding new light on the mystery, opening up the possibility that earhart may have ended up on the then—japanese—occupied marshall islands, and died as a prisoner. some are claiming the picture believed to be taken in the 1930s shows the pilot and her navigator fred noonan sitting on a wharf in jaluit atoll, after they went missing. but some experts dispute the claims. 0n of those, a little earlier, i spoke to ric 6illespie, founder of the international group for historic aircraft recovery, whojoined me from pennsylvania. i think it's incredible that something this silly has gotten as much attention as it has. it is always dangerous to hype a new allegation like this days before your television special and give people time to come forward with the information that completely debunks it and that's what's happening. it is a tribute to her i suppose

that people care so much, isn't it? that's exactly what it is. fill us in on that, why is she so significant to so many people? she was such an inspiration when she was alive. she was so famous. didn't hurt to be married to one the finest promoters since pt barnum. she really was a great personality and an inspiration. and she died at the height of her fame in a very mysterious manner. and then there were different theories about what happened to her and the controversy about that keeps her legend alive. and over the years it has become this iconic mystery. it is an addictive detective story, trying to figure out what really happened to her. and so a lot of people are really invested in various theories and there are still people,

although it has been debunked for years that she was captured by the japanese. and here we go again, probably because we live in an age of conspiracy theories. so ric, in a nutshell, or in a couple of nutshells, what is wrong with that picture? well, first of all, if this is amelia earhart, captured and in custody of the japanese, where are the japanese? there are no soldiers in this picture! this is a picture of a bunch of people standing on the dock. it is an office of naval intelligence photo taken atjaluit atoll, the headquarters of the japanese in the marshalls,

so they were curiouser about it. and the label on the photograph says that is where it is. it doesn't say anything about amelia earhart. nobody is acting like they are guarding everybody. everybody is just hanging out on the dock. the person that they claim is amelia earhart has her back to the camera, you can't see her face. if she is a woman. we know she has a lot more hair than amelia earhart had at that time she disappeared. we've got lots of good photos of her at the time. the guy they say is fred noonan, oh, absolutely — doesn't look like anything like fred noonan. for a lot of people air travel can be a bit of a chore. delays, queues, cramped conditions and food that often leaves a great deal to be desired. but once upon a time it was very different. travelling by air was exotic and exciting. now, a restaurant in los angeles is trying to recreate that golden age, as the bbc‘s tim allman reports. ah, those were the days, luxury at 14,000 feet. smiling stewardesses, businessmen in suit and tie, a different age. which you can now relive the pan am experience in la —

a restaurant designed to look like an airline. i actually had a lot of vintage menus from my days travelling pan am, so i picked my favourite one and i went to a caterer and got them to replicate the eact detail. that includes chateaubriand, carved at your table, chicken and peppercorn sauce, oh, and a vegetarian option — this is 2017, after all. and the chance to buy duty—free. it is the most brilliant experience, it really is. people of my age — old — we lived this, you know, we went through this. and it is gone. the airlines don't do what they used to do, pan am was the best and they always created the very best service. to operate the exit doors, simply push the door open. laughter.

mile—high entertainment, so to speak, at ground level. but it isn't cheap. their first—class tickets will set you back nearly $700. and, when you get out, you haven't travelled an inch. much more on that and all the news at any much more on that and all the news atany time much more on that and all the news at any time on the bbc website. and you can get in touch with me and most of the team on twitter. i'm @bbc mike embley. thank u for watching. —— thank you. it was a very warm day on thursday across england and wales, in particular southern and south—eastern areas, with a top temperature in london of 32 celsius. in fact, a number of stations in the greater london area saw 32 degrees and it was pretty hot as well further north,

but the heat across northern england broke down in spectacular style with some severe thunderstorms, we had reports of flash flooding and also some lightning damage across yorkshire and into lincolnshire. now, those thunderstorms will continue to rattle away off into the north sea, and then for most places it should be a dry end to the night. thicker cloud and outbreaks of rain, though, pushing into northern ireland and western scotland, it's going to be a very warm and muggy start to the day once again across the south, particularly the south—east. only a little bit of cloud around for the south—west of england, into western wales, but a good deal sunshine for the midlands eastwards and look at those temperatures to start the day, around 20 degrees. further north and there will be thicker cloud. for north—west england into scotland and northern ireland, like i mentioned, there will be some light and patchy rain around so a dismal morning with temperatures here at 8am around the mid—teens celsius. through the day it looks like that cloud across western areas will tend to move in eastwards and any clear skies tending to infill from cloud, so a cloudier afternoon that

what we saw on thursday, so that means not quite as hot. still very warm, though, in the south—east with 27 or 28 degrees. a rather low 20 further north and high—teens celsius in scotland and northern ireland. it means for the tennis at wimbledon on friday that it will be a bit more comfortable for the spectators and for the players with highs around 26 or 27 celsius and sunshine coming and going. a fine end to the day on friday, but we look to the west to this area of rain, which will push in towards wales, light and patchy and will affect mainly western areas. this weather front is responsible for it. as we head on in towards saturday it will bring a cloudy, damp day to central areas, northern ireland, through northern wales and into northern england, the rain not amounting to that much. to the north of it, largely dry with sunshine and there will be sunshine across southern areas, but generally speaking a cloudy day and a cooler one across the board. top temperatures 2a degrees. looks like temperatures rise a bit again as we head on towards sunday and that's because we pick up some thundery air again off

the near continent, this area of low pressure could introduce some heavy showers to southern parts of the country, maybe the odd thunderstorm, and this weather front brings outbreaks of rain to scotland and northern ireland. but in between a slice of drier and brighter weather and again quite warm in the south—east. this is bbc news, the headlines: 6erman riot police and demonstrators have clashed in the city of hamburg, on the eve of the 620 summit. police have used water cannon and pepper spray, as masked protesters clad in black threw bottles and stones, and started several fires. at least 70 officers were injured. in a speech on his arrival in europe, the us president donald trump called on western civilisation to stand united against what he called the menace of radical islamist extremism. trade, climate change and north korea are also expected to dominate the agenda at the summit. mexican authorities say 28 inmates have been killed in a fight in a prison in the coastal city of acapulco. three more were wounded.

security officials in 6uerrero state say the fight was between rival gangs. police say at least four prisoners were decapitated. now on bbc news, it's the travel show.
